Kong Zhen, an employee of Lusheng Group, accidentally met Ruan Zheng, the president of Ruan Shi Group, so Lu Yun, the head of Lusheng Group, sent him as an undercover agent to investigate leads about Ruan Zheng's twin brothers. What Kong Zhen didn't expect was that one of the twins turned out to be Liang Yu, his platonic love who was embarrassed in front of everyone ten years ago, but which one was he? Kong was really confused. After distinguishing the twins, Kong Zhen was plunged into the decision of helping Lu Yun find the murderer or helping Liang Yu, whom he once loved, get out of trouble. Kong Zhen wanted to find his former love, but discovered that Ruan Zheng already had his fiancée Xia Luo, and Yangyang also fell in love with Kong Zhen. The four of them struggled painfully in the whirlwind of misplaced love, between letting go or holding on tightly, admitting it frankly or continuing to act out. At the crossroads of fate, where will they go?.
